PRINT AND CARD CUTTING BOARD.

SPECIFICATION forming part of Letters Patent No. 679,167, dated July 23,1901.

Application filed April 6 1901.

following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference beinghad to the accompanying drawings,and to the figures of reference marked thereon, which form a part ofthis specification.

My invention relates to photographers print 'and form holding and printand card trimming and cutting boards; and the objects of my inventionare, first, to provide a photographers cutting and trimming board bywhich a form and print can be instantly clamped on or released from saidboard; second, to provide a combined print and form holder and acombined print or card holding and cutting board; third, to providemeans for adjusting the knife and operating-lever; fourth, to provide asimple, convenient, and practical card and print clamping and cuttingboard. I attain these objects by the mechanism illus trated in theaccompanying drawings, in which- Figure 1 is a perspective view of myimproved cutting-board. Fig. 2 is a side elevation of my cutting-board.Fig. 3 is a section of the cutting-knife and its actuating-handle online A and of the table and resilient clamping member on line B. Fig. atis a section on line C of Fig. 3; and Fig. 5 is a section of the spring,showing its side edge that faces the beveled board.

Similar numerals of reference refer to similar parts throughout theseveral views.

Referring to the drawings, the numeral 5 designates a board of anysuitable material. It may be made of any desired shape. Upon one sideand along one edge 6, which I will call the head portion of the board, Isecure a rule 7, which may contain any desired graduations of feet andinches. This rule also forms an abutting shoulder to place any articleagainst that it is desired to clamp to the board or that is to be cut.The rule 7 does not we tend all the way across the board, a narrowSerial No. 54,724:- (No model.)

space being left between one of its ends and the adjacent edge 8. Thisedge 8 is formed at right angles to the top end and to the rule twovertically-projectinglugs 17 and 18,which are integral with the baseportion. Through the central portion of the ears of the clip I place abolt 19, upon the central portion of which, between the ears, I securepivotally one end of a long lever 20, which forms thef7o actuating-leverof the cutting-board. At the opposite end of this lever I place asuitable handle 21. I secure pivotally to the bolt 19 one end of a thinresilient blade 22, which is preferably made of spring-steel orspringbrass. The end of the spring that is secured to the bolt 19 has aslot 23 formed in its central portion,which divides its end portion intotwo separate ends. These ends are formed into hub portions 24 and 25,which are mounted loosely on the bolt 19, between the ears of the clip,on opposite sides of the lever 20, which restson the bolt in the slot,between the hub portion of the ends of the spring.

This spring-blade is curved downward sharply from the bolt 19, so thatit strikes the surface of the board at the end of the rule, and isarranged with its adjacent edge close to the rule. The spring-blade ispreferably wider than the lever 20 and extends from the 0 bolt in aconvexed curve under the lever 20 to close to its handle 21, where asemicircular hook 26 is formed. This hook is formed on preferably butone side of the springblade and is arranged to surround a pin 27, 5

which projects from the adjacent side of the lever 20 and secures thefree end of the spring-blade to the lever, so that if the handle israised up the spring-blade will be lifted with it by the engagement ofthe pin with its 1 oo hook. The radius of the curve of the springbladeis'such that when its sharp downward curved portion at its pivotal endrests naturally on the board at the rule its oppo- I secure 6o site freeend will support the lever and handle at an upward angle of preferablyfrom about twenty to thirty degrees. When the handle is pressed down,the spring blade flattens out underneath it against the surface of theboard, its hook leaves the pin, and its free end slides along the underside, as shown which comprises, preferably, a crank-shaped piece of wirehaving a projecting flange portion 30 adjacent to one end, which restson top of the board, and an end 32 projects from the flange and extendsthrough the board, and a round head 32 is threaded or otherwise securedto its end. When the handle and spring are pressed down against theboard, they can be locked in that position by swinging the right-angledportion of the keeper over the lever, as shown in the dotted lines inFig. 2. The extreme end of the shear blade adjacent to the clip 12 iscurved upward into a lug 33, to the center of which a headed screw 33 isthreaded, to which I piv- F otally secure one end of a knife-blade 34. rThe pivotal center of this knife and shear blade is placed below thepivotal center or bolt 19 of the spring-blade and is preferably placedsubstantially in a vertical plane below the bolt 19.

The pivotal end of the knife is curved upward enough to bring its topedge about even with the top of the lever 20 and then extends along thelever substantially parallel with it to about the end of the spring. Theknife is preferably made a little wider than the lever The free end ofthe r and depends below it. knife is secured to the lever 20 by a screw35,

which projects from the adjacent side of the 1 lever through a slot 36,which is formed in the free end of the knife-blade. 35 is provided witha screw-driver head 36,

by which it may be turned to adjust the adjacent end of a knife relativeto the shearblade below it. As the centers of the springblade and theknife are placed a short distance apart and as they both engage thelever at about the same point, they havea 'relative differentialmovement which results as the lever is pressed down in the springsbearing against the board ahead of the cutting edge of the knife. Theweight of the handle "andknife and spring-blade keep the springbladeresting normally against the board adf jacent to its pivotal end withits bearingpoint on the board a short distance ahead of the intersectingcutting edges of the shearblade and the knife-blade.

My combined print and form holder and cutting-board is especiallyintended for and is especially adapted as a print trimming and cuttingand a form and print clamping board This screw for photographers use;but it is obvious that it can be used as a general cutting-board formeasuring and cutting papers, cards, cloths, fabrics, dice. It can alsobe used to cut thin sheet steel, iron, copper, and brass.

The operation of cutting any material simply consists in raising thehandle and springblade and knife and placing the material to be out onthe board preferably against the rule and then forcing the spring-bladeand knife down against the board. The springblade clamps tightly by itsresilient pressure the article against the board ahead of thecutting-point of the knife.

When using the board for cutting out photographers prints from aform,the-operation is as follows: The handle and spring-blade are raised, andthe print 40 -(see Fig. 1) is placed on the board with one edgeextending over into the path of the spring-blade and with another edgepreferably against the rule. The form 41 is then placed on top of thepoint, and one edge of it is also extended into the path of thespring-blade. The handle and spring-blade are then carried down againstthe board with one hand and the keeper is turned to extend over thelever with the other hand, and the handle and lever are locked to theboard with the spring-blade resting with its full resilient pressure onthe top of the form, thus clamping it and the print tightly to theboard. The form contains an aperture 42 in its central portion, whichmay be of any desired shape or outline, and a knife is run around theinner peripheral surface of the aperture, and that portion of the printthe aperture covers is cut out.

My invention is very simple, useful, dura ble, and inexpensive.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-
